    What is Centripetal Force?

    Centripetal force is defined as,Continue Reading Centripetal And Centrifugal Force – Physics Notes – For W.B.C.S. Examination.

    The component of force acting on an object in curvilinear motion which is directed toward the axis of rotation or center of curvature.

    The unit of centripetal force is Newton. The centripetal force is always directed perpendicular to the direction of the displacement of the object.

    If an object accelerates according to the changes of velocity, then it can change either its speed or direction of motion. In simple terms, if any moving object in a circular path is constantly changing its direction means it is constantly accelerating. Using Newton’s second law of motion, if an object is travelling in a circular path, it is found that the centripetal force of an object moving in a circular path always acts towards the centre of the circle.

    How is the Centripetal Force Calculated?

    The Centripetal Force Formula is given as the product of mass (in kg) and tangential velocity (in meters per second) squared, divided by the radius (in meters). Which implies that on doubling the tangential velocity, the centripetal force will be quadrupled. Mathematically it is written as:

    F=mac=mv2r

    Where,

    • F is the Centripetal force.
    • ac is the Centripetal acceleration.
    • m is the mass of the object.
    • v is the speed or velocity of the object.
    • r is the radius.

    What is Centrifugal Force?

    If an object moving in a circle and experiences an outward force than this force is called the centrifugal force. However, the force also depends on the mass of the object, the distance from the centre of the circle and also the speed of rotation. If the object has more mass, the force of the movement and the speed of the object will be greater. If the distance is far from the centre of the circle the force of the movement will be more.

    The Centrifugal Force is defined as,

    The apparent force, which is equal in magnitude and opposite in direction to the centripetal force, drawing a rotating object away from the center of rotation, caused by the inertia of the object.

    Centrifugal force unit is Newton. The centrifugal force drives the object away from the centre. It is a fictitious force.

    How is Centrifugal Force calculated?

    Centrifugal Force Formula is given as the negative product of mass (in kg) and tangential velocity (in meters per second) squared, divided by the radius (in meters). Which implies that On doubling the tangential velocity, the centripetal force will be quadrupled. Mathematically it is written as:

    Fc=mv2r

    Where,

    • Fc is the Centrifugal force
    • m is the mass of the object
    • is the velocity or speed of the object.
    • r is the radius.
